SCOTTSDALE, Ariz. -- Devin Gardner's season is over, and it's unclear as to when, exactly, he'll be able to be at full strength again.

On Thursday, Michigan coach Brady Hoke announced that freshman quarterback Shane Morris will be the team's starter in the 2013 Buffalo Wild Wings Bowl on Saturday (10:15 p.m., ESPN) against Kansas State in Tempe, Ariz.

Morris is starting because Gardner, the team's starter all season, has yet to recover from a foot injury suffered against Ohio State at the end of November.

Hoke said Michigan tried to get Gardner ready to play, but couldn't do it. On top of that, he added that Michigan is concerned about the possibility of broken bones in Gardner's injured left foot.

"I think that's what they're worried about, the slight fractures, that kind of stuff," Hoke said. "I don't know. They've x‑rayed it a couple different times. They (took an MRI).

"It's probably just a little more than just the turf toe."

While Hoke speculated that Gardner may have a broken foot, CBSsports.com's Bruce Feldman reported -- citing an unnamed source -- that Gardner's foot is indeed broken.

Feldman reports that Gardner suffered the injury on the second drive of the third quarter against Ohio State. If true, that means Gardner led the Wolverines on three touchdown drives with a reportedly broken foot.

Gardner, who was not present at Michigan's media day Thursday and hasn't spoken publicly since the Ohio State game, will finish his season with 2,960 yards passing, 21 touchdowns and 11 interceptions.

His 2,960 yards rank second on Michigan's all-time single-season passing list. His 3,443 total yards were the second-most of anyone in the Big Ten this season.

Asked earlier this month if Gardner, a fourth-year junior, was potentially considering an early exit to the NFL rather than playing his final year in Ann Arbor, Hoke would not comment.

On Thursday, Hoke wasn't talking about the NFL, though.

He was talking about whether or not Gardner's injury would be healed up in time for spring practice in March.

"I think he's improving, that's just the way it has to heal up," Hoke said. "He should be ready when we get to spring.
